This invention relates to concealed hinges. More particularly, itrelates to an improved, concealed hinge for use in automobiles and likevehicles, said hinge being adapted to be concealed and attached in adoor and car frame.

The present invention has for an objectto pro- Vide a concealed hingewhich is easily made but preferably from any suitable sheet metal andwhich is of superior mechanical features than any heretofore used.

Another object of the present invention is to provide a hinge whereinthe sides thereof are readily attachable to a door and frame of a car.

One other object of the present invention is to provide a concealedhinge for use in automotive vehicles and the like, adapted to eliminaterattling of the doors in which said hinge is used.

Still another object of the present invention is to provide a hingehaving a movable portion disengageable from a main portion of said hingeto permit easy removal of a door froma frame when said hinge is used.

A further and more specific object of the present invention is toprovide a hinge having a fixed portion provided with a guideway adaptedto retain a guide connected with a movable portion of the hinge, saidguide being also adapted to check the opening of a door to which it isconnected.

Another object of .the present invention is to provide a concealed hingein connection with a door and frame adapted to be disengaged to permitremoval of the door from the frame without the removal of screws and thelike as used heretofore in hinges.

Other objects and features will become apparent upon reading thefollowing detailed description of the embodiment of the presentinvention.

The invention generally consists in the features of novelty appearing inthe construction, arrangement and cooperation of the several partshereinafter fully described and is taken in connection with theaccompanying drawing, in which Fig. 1 is a vertical front view of apreferred embodiment as mountedin a frame and door frag: mentally shown.

Fig. 2 is a vertical sectional view of my embodiment.

Fig. 3 is a plan View taken on line 3-3 looking in the direction of thearrows in Fig. 2, and

Fig. 4 is a plan view of Fig. 1.

Fig. 5 is a perspective view of the stationary part of my embodiment.

Referring now to the drawing, in which like reference charactersdesignate like parts throughout, aframe section A of an automobile orother vehicle is recessed to accommodate thenon-movable portion of thedevice as shown in Figs. 1 and 4. Said portion is made of any suitablematerial such as sheet metal blanks and is preferably of rectangularshape with a front and two opposed side walls as shown. The walls 50, IIand I2 respectively, of said portion are provided with a plurality ofopenings [3, Hi and 15 respectively, into which fit screw members (notshown), for fixing the portion to frame section A. Said portionfurthermore, is provided with a pair of spaced, parallel, horizontalplates it and I'L'respectively, fixedto the vertical walls as shown inFig. 2, being joined thereto and forming a part thereof, by any suitablemeans well known in the art. It is to be noted that the front wall Id atits upper portion has an opening l8, continuing along a reduced slot l9and a wider continuing curved slot 28 in the upper horizontal plate.Furthermore, the front wall is provided with an opening 2| into whichfits a screw or rivet member'22 forpivotally holding a safety catch E,while the upper horizontal plate has an opening 23 for a rivet member 24retaining a check D. Said check D can be swung outwardly of the verticalfront wall Ill and around the rivet as an axis and has upwardlyertending spacedlug ends 25 and 26, respectively adapted to fit into thecorresponding opening 48 andbe retained therein by means of said catch Ethus closing said opening.

Said lower horizontal plate I6 is provided with a curved slot 2'! and aslightly reduced curved guide slot 28 and 29. His to be noted that slot21 is substantially of the same size as slot 2% and disposed directlybeneath said latter slot for purposes hereinafter described in detail.

Adapted to coact with the non-movable section of the hinge abovedescribed and shown in the drawing, there is provided a movable hingemember GH having a plurality of vertical side walls 30 and 3|,respectively and a face wall 32 integral therewith as shown in thedrawing. Said fitting into the space between thehorizontal par- 55 iallel plates and I1 and has an opening 34 for accommodating a pintle 35.It is to be noted that said pintle has a plurality of sections ofdifferent diameters along its length as shown in Figs. 1 and 2. ,Section36 is the top portion of the pintle adapted to fit in slot and slidetherein, while section 31 is reduced and fits in the space intermediatethe horizontal plate members. Section 38 of the pintle on the otherhand, is of substantially the same diameter as section 36 and is fittedor swaged into position in opening 34 of the hinge member G--H. Thelowermost portion of the pintle has a relatively wider section 39adapted to slide in slot 21 in the lower hori- N zontal plate as shownin Fig. 3 of the drawing. It is to be noted from the above descriptionof the pintle that it is fitted at right angles to the longitudinal axisof member G-H. Furthermore,

each section of the pintle has a particular funcwith the wider curvedslot of the other member, a

tion in the operation of the hinge member.

In order to limit the outward and inward movement of said hinge memberG-H, there is provided a guide member 43 adapted to fit in the recess 4|provided therefor, on the curved arm of member G-I-I. Said member has arecessed portion 42 adapted to travel in slot 28-29 in lower plate I6 asshown in Fig. 4. Furthermore, guide member 40 is fitted into slot 28 and29 by initially placing same in the reduced portion 28 of said slot. Itis to be noted that once the movable hinge member G-H is mounted, it canbe slidin or out as desired without coming apart from the fixednon-movable portion mounted in section A, as shown in Figs. 1 and 4 ofthe drawing.

In order to assemble and operate the device as disclosed herein, thepivoted safety catch member E is swung about its pivot so that the freeend thereof is raised to form contact with the upwardly extending spacedlugs or ends 25 and 26 of check D. Said check D is swung outwardly onits pivot to permit the insertion of the pintle into slot l920 and theinsertion of guide into slot 28-29. This having been done the check D isclosed and engaged with safety check member E, as shown in Figs. 1 and2. It is to be noted that the space between the two horizontal plates isof sufficient depth to permit the slight raising of hinge member G--Hfor proper insertion into the slots above indicated without permittingany unnecessary rattling.

In the operation of the hinge above described, the movable section G-Hbeing mounted onto a door may be moved in and out of the fixed sectionC. In such cases, the pintle 35 having parts 36, 31, 38 and 39 mountedon curved arm GH moves in slots 20 and 21, while guide member 40 movesin slot 28, 29 and retains the movable section of the hinge in operableposition without becoming separated from fixed section C. The device asdescribed hereinmaybepreferablymade of sheet metal blanks of anydesirable shape and then bent to form the embodiment as shown in thedrawing herein.

The device as described is adapted for either straight line or curveddoors of automobiles or other vehicles or even building doors. Thedevice can be easily mounted and the width of the fixed portion can bevaried to suit the particular type of application. Also, the devicepermits of a snug fit in the door frame, while the removable portion isfixed to the door by means of rivets or like means.

, It is to be noted that the, embodiment as disclosed herein inconnection with the accompanying drawing, is an improvement on theinventions disclosed in my patents numbered 1,633,480 and 1,646,644granted June 21, 1927, and Oct. 25, 1927, respectively.

While one preferred form of my invention has been described inconnection with the accompanying' drawing, it is understood that variousmodifications as to form, material, arrangement and use of materials maybe made without departing from the spirit and scope of my invention.
